Examples

The following example shows a DataGridHyperlinkColumn that sets the Uri with the Binding property and the hyperlink text with the ContentBinding property. The Hyperlink.Click event is handled automatically because NavigationWindow is the parent of the DataGrid.

<NavigationWindow x:Class="DataGrid_CustomColumns.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:core="clr-namespace:System;assembly=mscorlib"
    xmlns:local="clr-namespace:DataGrid_CustomColumns"
    Title="Customers" Height="300" Width="300" ShowsNavigationUI="False"  >
    
<NavigationWindow.Resources>

    <!--Create an instance of the converter for Email-->
    <local:EmailConverter x:Key="EmailConverter" />
</NavigationWindow.Resources>
<NavigationWindow.Content>  
    
<Grid>
    <DataGrid Name="DG1" ItemsSource="{Binding}" AutoGenerateColumns="False" >
        <DataGrid.Columns>

<!--The Email property contains a URI.  For example "mailto:[email protected]"-->
<DataGridHyperlinkColumn Header="Email" Binding="{Binding Email}"  ContentBinding="{Binding Email, Converter={StaticResource EmailConverter}}" />

            </DataGrid.Columns>
        </DataGrid>
    </Grid>
    </NavigationWindow.Content>
</NavigationWindow>

Remarks

Use DataGridHyperlinkColumn to display data that contains a Uri, such as an HTTP address or email address. The following illustration shows an example of a DataGridHyperlinkColumn.

To populate the column, bind the column to the Uri data by using the Binding property. To display hyperlink text that is different than the URI string, bind the text value to the ContentBinding property. The Binding property is applied to the Hyperlink or TextBox element created in the column. The DataContext for the element in each cell is the data item for the row the cell is in. Therefore, to set up the binding you only have to set the Binding.Path. Optionally, you can specify a Binding.Converter if you want to convert the data. For more information about data binding, see Data Binding (WPF).

If you want to display other types of data, DataGrid provides the following column types:

If you want to use other controls in your DataGrid, you can create your own column types by using DataGridTemplateColumn.
